Donald Fagen, Michael McDonald and Boz Scaggs brought a tractor-trailer’s worth of hits — both as solo artists and with Steely Dan and the Doobie Brothers, respectively — to this setlist. More important, however, was their simpatico sense of musical camaraderie.

The joy surrounding this blues-rock collaboration is found not just in the Rides’ meaty originals — four of the 10 tracks are new — but in the way this just-founded trio happily attacks the cover tunes.
